Just played about 3 hours with Proton-5.11-GE-MF and it works flawlessly, no performance issues (except that of my machine limitations) and intro videos work.
I experienced sometimes the performance drops to a crawl. No way to fix it in-game, just exit and restart, everything will be back to normal. It happened twice in scripted non-controllable scenes.
After working around this the game work with Prtono 5.13-2 RC but no videos play
Relicta's DX12 mode started working with Proton 6.3-4 for me but has some visual bugs (flickering shadows). No problems with DX11.
